一、引言我们曾经介绍过耐酸碱、低收缩、高频绝缘性能优良的二甲苯不饱和聚酯树脂2608(见本刊1982年第六期)该树脂已在我国建筑防腐蚀工程、雷达设备、电视机元件中广为应用,并已投入工业化生产。由于该树脂在强应力下,仅能于70℃以下应用,不能适应高温下化工设备及电器设备的高温绝缘要求。考虑到国外耐腐蚀、电绝缘用树脂,多
I. INTRODUCTION We have introduced 2608 xylene unsaturated polyester resin with excellent acid and alkali resistance, low shrinkage and high frequency insulation properties (see our journal No. 6, 1982). The resin has been used in China’s construction anti-corrosion engineering, radar equipment , TV components widely used, and has been put into industrial production. As the resin under strong stress, only 70 ℃ below the application, can not meet the high temperature chemical equipment and electrical equipment, high temperature insulation requirements. Taking into account foreign corrosion resistance, electrical insulation resin, and more
